CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 290,276, dated December 18, 1883.

Application filed September 27, 1883. No model.)'

To all whom it may concern.-

Be it known that I, HENRY L. SHIREMAN, a citizen of the United States, residing at Nazareth, in the county of Northampton and State of Pennsylvania, have invented a new and useful Gar-Coupling, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to car-couplings, the object being to provide improved devices for automatically coupling the cars which shall be cheap, simple, and durable in their construction, and which shall thoroughly effect the automatic coupling of the cars.

The invention consists in the improved construction of coupler hereinafter fully described, and pointedout in the claims.

In the drawings, Figure 1 is a front elevation of my improved coupling devices applied to a car. Fig. 2 is a longitudinal vertical section of the same, and Fig. 3 is a transverse vertical section on the line so as of Fig. 2.

A represents a car, to the under side of which is secured a buffer or bumper, B, which consists of two parallel beams.

0 represents a bar beveled on its front face, as shown, and which is adapted to receive a coupling-hook of an adjacent car, its ends being provided with blocks 0 c',which are formed integral therewith and secured to the under sides of the beams forming the bumper at their front ends.

D represents the draw-bar, which is provided with a longitudinal perforation or slot near its rear end,and pivotally secured in a recess, d, formed in the front end of the block d,by means of a rod or pin passing through the slot 61 in the end of the draw-bar, which fastening allows of thelongitudinal movement of the said draw-bar D. The block dis providedwith an interior longitudinal recess for the reception of a coil-spring, (Z against which bears the rear end of the draw-bar D.

E represents a spring pivotally secured to the under side of the car, directly above the draw-bar, and engaging therewith to prevent the bar from being lifted by the motion of the cars. This spring is formed with a slot, 6, to engage a pin, 6, extending upwardly from the draw-bar, and for the purpose of shifting the spring with the draw-bar in turning curves, 820.

F represents a block secured to the under side'of the car, to limit the lateral movement of the draw-bar D. The front end of the draw bar D is beveled, and provided with a coup ling-hook, H The said coupling-hook H is also slotted to receive a coupling-link, and provided with a vertical perforation to receive a coupling-pin.

On the under side of the bumper B are secured depending blocks or boxes I) b, forming bearings for trunnions 1) b formed upon the ends of a plate or latch, G, for raising the draw-bar when it is desired to uncouple the cars. This latch is beveled 011 its front face, to facilitate its operation and to prevent it from catching on the draw-bar when the said draw-bar is to be released from engagement with the adjacent car.

On the inner sides of the depending blocks 1) b are secured cam-shaped blocks g, which limit the forward movement of the plate-or latch G. One of the trunnions b of the latch G extends laterally beyond the buffer B, and has mounted thereon a collar, H, adjustable on saidtrun'nion by means of a set-screw, g.

I represents a lever pivoted in a recessed block, a, secured to the end of the car, and connected to the collar H by means of a rod, J. This lever I is used for the purpose of uncoupling the cars by means of the rod-connection J with the collar H, which is rigidly mounted on the trunnion'of the plate or latch G.

The operation is as follows: When the cars are to be coupled,they are brought in contact, the draw-bars of each car striking against the beveled bar secured to the under side of the bumper of the opposite car, and their hooked ends engage said bars,the spring E preventing the ,draw bar from becoming disengaged. When the cars are to be uncoupled, the lever I is pushed toward the opposite side of the car, and in so doing raises the latch G from a horizontal to vertical position, as shown in Fig. 2. The latch bears against the under side of the bar, and raises the same from engagement with the next adjacent car.

Having fully described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is-

1. In a car-coupling, the combination of the buffer, comprising two parallel beams, a bev buffer, comprising two parallel beams, a beveled bar connecting the under front ends of the buffenbeams, boxes secured to the under sides of the buffer-beams, a latch, G, having trunnions bearing in said boxes. cam-shaped lugs secured to the inner sides of said boxes, a

draw-bar having a coupling-hook at its front end and a longitudinal slot near its rear end,

a block secured to the under side of the car, and having a longitudinal recess and a slot in its under side, a coil-spring seated in said block, and a transverse pin hinging the drawbar in the said recessed block, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

HENRY L. SHIREMAN.
